Hi, I am wondering, does anybody knows if there is any package/function in R I can use to calculate the espresso heuristic logic minimizer ? (http://en.wikipedia.org/wiki/Espresso_heuristic_logic_minimizer) Also, would you please kindly let me know if there is any open source computer algebra system which has the espresso algorithm implemented.
